Sensor BlocksThis through transmission module realizes the mutual conversion of TTL signal and RS485 signal, but we must know that 485 is half duplex communication, this communication mode can realize two-way communication, but it can not be carried out in two directions at the same time, it must be carried out alternately; that is to say, each end of the communication channel can be the sending end, or the receiving end, but at the same time, the information can not be transmitted There can only be one transmission direction.Baud rate: 110 ~ 128000bps, supportModule highlights:(1) 3.3V compatible with 5.0V power supply(2) 3.3V compatible with 5.0V signal(3) , industrial grade design, strong anti-interference ability, and more effective 485 protection design, which can be used in the harsh environment of industrial site and field, with the working temperature of - 40 to + 85 , and the transmission distance of up to km (test with 850 meters of 2 * 1.5 cable, it is recommended to use within 800 meters, and add repeater if more than 800 meters)(4) Adopting half hole process design, the thickness of the plate is 0.8mm, which can be easily used as a sub mother plate or welding terminals(5) With RXD, TXD signal indicator, you can get a panoramic view of the receiving and sending situationModule features:(1) This module fully considers the protection design and anti-interference design of 485 bus. In the field long-distance transmission, connecting the "Earth" end of the module to the earth can play a good role in anti-interference and protection, making 485 bus safer; in the indoor short-distance transmission, it can not be connected to the earth.(2) The standard 2.54 spacing design is adopted to facilitate your secondary development(3) With 120 ohm matching resistance, short circuit R0 can make matching resistance, short circuit is recommended for long distance transmission.(4) It supports multi computer communication and allows to connect to the bus of 128 devices(5) The module can be pluggable, and there will be no signal blocking phenomenon of other 485 chips pluggable(6) Lay copper in large area to prevent signal interference
